Aren't you better to run the MVHR at the normal speed. Then the MVHR actively pulls the humidity out the house, moving dew point upwards.

Generally yes, but only if humidity is lower outside than in.

Where I am, humidity is still high, and is forecast to rise through the night into the high 80s. Thankfully it should drop a fair bit through tomorrow.

 

Here too. We're only a mile from the Solent, so external humidity is generally higher.

Interesting topic - Heat Geek have just released a video on the subject and there was one thing that got my attention bearing in mind I am all rads (no UFH) and they are almost all converted to TBOE from a flow perspective - I will one day convert to heat pump but when the boiler dies or Gas v Electricity cost perspective drives the change.
